Which protocols/ports does JDisc Discovery use to discover devices on the network?
Category:
Discovery
The list of protocols depends on the device type. Different devices support different protocols. For example, a Windows computer primarily uses the Windows registry and WMI. Linux computers are identified via telnet or SSH, whereas most switches are identified via SNMP.
The table below lists all ports and protocols used by JDisc Discovery:
| Protocol | Port |
|---|---|
| Domain Name System (DNS) | 53 (TCP) |
| Hypertext Transfer Protocol (HTTP) | 80 (TCP) |
| Hypertext Transfer Protocol Secure (HTTPS) | 443 (TCP) |
| Lightweight Directory Access Protocol (LDAP) | 3268 (TCP) |
| Lightweight Directory Access Protocol (LDAPS) | 3269 (TCP) |
| Network Basic Input/Output System (NetBIOS) | 137 (UDP), (UDP) and 139 (TCP) |
| PING | n/a |
| Redfish | 443 (TCP) |
| RPC Endpoint Mapping | 135 (TCP) |
| S7comm (Siemens SIMATIC PLCs) | 102 (TCP) |
| Secure Shell (SSH) | 22 (TCP) |
| Simple Network Management Protocol (SNMP) | 161 (UDP) |
| Server Message Block (SMB) | 445 (TCP) |
| Telnet | 23 (TCP) |
| VMware API (VIM SDK) for VMware Server | 8333 (TCP) |
| VMware API (VIM SDK) for VMware ESX Server | 443 (TCP) |
| Web Based Enterprise Management (WBEM) | 5989 (TCP) |
| Windows Remote Login | Uses the SMB Protocol |
| Windows Remote Registry | Uses the SMB Protocol |
| Windows Management Interface (WMI) | 135 (TCP) and a random (ephemeral) port that depends on the Windows version. |
